Specification of Letters Patent.

Application filed December 7, 1917. Serial No. 205,923.

T 0 all whom. it may concern:

Be it known that I, HERBERT J. HOPE, a citizen of the United States, residing at Sanford, county of York, State of Maine, have invented an Improvement in Pile-Fabric Looms, of which the following description,

- in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to pile wire looms and has for its object to provide a novel pile wire loom by which a pile fabric having both long and short pile can be woven. I accomplish this herein by employing a pile wire loom which operates with both knife wires and'hook wires. In operating the loom pile loops are formed over both sets of wires, and the knife wires are withdrawn the pile loops which are formed thereover will be cut, while when the hook wires are withdrawn the loops which are formed thereover will be engaged by the hook and will be drawn out thereby to withdraw one end of each of said loops from the fabric. By this means a fabric with a long pile can be produced.

In order to give an understanding of my invention, I have illustrated in the drawings a selected embodiment thereof which will now be described after which the novel features will be pointed out in the appended claims. I

Figure 1 of the drawings is a plan-view of a pile wire loom embodying my invention;

Fig. 2 is a View of one-of the hook wires;

Fig. 3 is a similar view of one of the knife wires; f

Fig. 4 is a diagrammatic View showing the way in which the knife and hook wires cooperate to produce'the pile fabric having the long pile;

Fig. 5 is a view illustrating the character of the pile fabric w iich is made on my improved loom.

The main features of my improved loom are or may be of any usual construction, and in Fig. 1 of the drawings I have illustrated -a plan View of a pile wire loom of known construction which has embodied therein.

In the drawings 1 indicates the loom frame which carries the usual warp beam 2 from which the warp threads are taken; lay having the shuttle my improvements boxes 4 and which is operated from the 5, and 6 indicates the cloth roll crank shaft on which the cloth is wound up as it is woven. These parts are or may be all as usual in pile wire looms and form no part of my present invention. The pile wire motion may also be of usual construction and that herein shown comprises the wire carriage or slide 7 which slides back and forth on the horizontal bar or support 8 and which is given its reciprocating movement by suitable connections operated from the shaft 9 that in turn is geared to and driven by the shaft 10. The pile wires which are woven into the fabric are indicated generally at 11, each pile wire being provided with the usual head 13.

12 indicates the magazine in which the pile wires are received when they are inserted into the shed and 14 is a guiding trough through which each he is introduced into the shed and into wire is placed as it is withdrawn from the fabric. This trough 14 is pivotally mounted at its outer end and any usual means may be provided for swinging it toward and from the front of the loom so as to be positioned properly to guide each wire into the shed when it is inserted and to receive each wire as it is withdrawn. The above elements may have any suitable or usual construction and form no part of my present invention, and as the operation of the device as thus far described is familiar to those skilled in the art, I have not deemed it necessary to enter into a more detailed description of the loom itself.

which each In accordance with my improvements I employ pile wires of special construction, that is, certain bf the knife wires, such as shown. in Fig. 3, and others of the pile wires are so-called hook wires and may have a construction such as shown in Fig. 2. The knife wires I have indicated at 15, each wire having the knife portion 16 at its end. The hook wires are indicated at 17 and each of these hook wires is provided at its outer end with a hook portion 18. These hook wires and knife wires may be introduced into the fabric as it is woven in any predetermined order, depend ing on the character of the fabric to be produced. In the drawings I have illustrated them as introduced alternately, that is, during one wire-inserting movement of the wire carriage 7 a knife wire will be inserted, and during the next wire-inserting movement a hook wire will be inserted, while during the pile wires are ordinary third wire-inserting movement a knife will be inserted agaln and so on. W 1th threads,

over, and the cutting wire this plle loops formed arrangement there will be and when each over each of the pile wires,

knife wire 15 is withdrawn the knife 16 thereon will cut the loops formed over said wires, while when each hook wire 17 is withdrawn, the hook l8 thereon will engage the pile loops thereby producing a long pile. oration is diagrammatically illustrated in Fig. i wherein l matically a portionof a pile fabric having the knife and hook wires woven thereinto. in said figure 19indicates the body warp 26 indicates the pile warp threads and 21 indicates the filling threads, the warp threads and filling threads being interwoven in usual manner. Each pile warp 20 is illustrated as looped singly over two adjacent pile wires and then is interwoven into the fabric neXt two adjacent pile wires and then formed into two loops which are looped over the next two adjacent pile wires, etc. Each pile warp thread 20 will thus have pairs of loops formed therein, the loops of each pair being indicated at 22 and 23, respectively. The loop 22 of eachpair is formed over a knife wire and the loop23 is formed over a hook wire. Any suitable relative arrangement of the pile warp threads and the body warp threads may be employed without affecting the invention. With the knife wires and hook wires thus alternately introduced and woven into the fabric and with the pile loops formed thereover, as shown in Fig. i, it will be seen that when each knife wire is withdrawn the knife 16 thereon will sever all of the loops 22 which are formed thereof these loops will leave the two loop ends 25, 26. When the next pile wire which is a hook wire 1'? is withdrawn, the hook l8 thereon will engage the loops 23 and will draw out these loops thereby withdrawing from. the fabric the leg 27 of the loop 23 and the end 26 of thecut loop 22 thereby forming a long pile 28 which is formed from the loop "23 and the leg 26 of the cut loop 22. The other leg 25 ofeach cut loop will remain projecting formed thereover and draw one I end of each of the loops out from the fabric lhis ophave shown diagramv thread for the space occupied by the meanest" from the fabric as a short pile, and 'a pile fabric can thus be produced directly ona wire loom which has a relatively long ile gile. By using mohair or similar material for the threads from which the pile loops are formed, it is possible to weave a pile fabric which'closely resembles the fur of an animal having relatively long hair.

I claim:

1. In a pile wirelooin, the combination with means to interweave warp and filling threads and to form pile loops in certain of the threads, of means to out certain of the loops, and means to pull out from the fabric the uncut loops.

2. In a pile wire loom, the combination with means to interweave'warp and filling threads and to form in certain of the threads pile loops which are arranged in pairs with the loops of each pair closely adjacent to each other, of means to cut one loop of each pair, and means to pull out from the fabric the uncut loops of each pair thereby to produce a long pile.

8. in a .pile wire loom, the combination with means to interweave warp and filling threads, of hook pile wires and knife pile ,engaging hook adapted when said wire is withdrawn from the fabric to engage the.

pile loops formed thereover and withdraw said loops'from the body of the fabric.

5'. A pilewire of the type constructed to be woven into a pile fabric during the weaving of the latter, said pile wire having a body portion of a length equal at least to the width of the fabric, and a hook portion at one end beyond the portion which is woven into the fabric.

in testimony whereof, I have signed my name to this specification.

' HERBERT J..HOPE.
